The viscerocranium is the pharyngeal skeleton. It is derived only from the neural crest and undergoes [[Bone and Cartilage Development - Anatomy & Physiology|endochondral and intramembranous ossification]].

The various facial muscles attach onto the skull in different places depending on their function. Movement of the external apendages, [[Mastication|mastication]] and facial expressions all rely on the movement of the facial muscles.
